What Does “Duration of Status” Mean for International Students and Exchange Visitors?

International students and exchange visitors often encounter several different dates on their immigration documents. A visa may have one expiration date, while a Form I-20 or DS-2019 has another. The electronic Form I-94 may not show a date at all and may instead contain the letters “D/S.” Understanding how these documents work together is essential because a visa’s expiration date does not necessarily determine how long someone may remain in the United States.

For many F and J nonimmigrants, admission for “duration of status” has long provided flexibility to complete an authorized academic program or exchange activity without requesting a new period of admission every time the original timeline changes. A recently issued Department of Homeland Security rule would have replaced that framework with fixed admission periods. However, a federal court postponed the rule nationwide on September 14, 2026, one day before it was scheduled to take effect. For now, duration of status remains in place.

What does “D/S” mean?

“D/S” stands for “duration of status.” When D/S appears on a person’s Form I-94, it generally means that the person may remain in the United States for the period during which they are pursuing the authorized activity connected to their classification, provided they continue complying with the applicable immigration requirements.

For an F-1 student, that usually includes the authorized course of study, any properly authorized practical training, and the applicable departure period. For a J-1 exchange visitor, it generally includes participation in the approved exchange program shown on the DS-2019, plus any applicable departure period. The precise rules depend on the classification and individual circumstances.

A visa expiration date is not the same as the authorized period of stay

One of the most common sources of confusion is the difference between a visa and immigration status. A visa is primarily a travel document used to request admission at a U.S. port of entry. The Form I-94 records the classification and period of admission granted after entry.

As a result, a visa may expire while a student or exchange visitor is still lawfully present in the United States. An expired visa does not automatically end a valid period of stay. However, if the person leaves the country, a new visa may be needed before returning. The I-20 or DS-2019 also remains important because it documents the program and must be kept accurate and properly endorsed when required.

Duration of status does not mean an unlimited stay

Admission for duration of status is flexible, but it is not indefinite permission to remain in the United States. F and J nonimmigrants must continue following the rules of their classification. A person can violate status even if the Form I-94 says D/S.

Depending on the classification and circumstances, maintaining status may require:

· Remaining enrolled in the required course load or participating in the authorized exchange program.

· Keeping the Form I-20 or DS-2019 accurate and valid.

· Obtaining authorization before employment, practical training, a reduced course load, or another activity that requires approval.

· Following the proper procedure before transferring schools, changing educational levels, extending a program, or changing an exchange program.

· Updating the school or program sponsor after certain changes, including an address change.

· Departing, transferring, or taking another permitted step within the applicable timeframe after completing or ending the program.

The exact requirements are fact-specific. Students and exchange visitors should communicate with their designated school official or responsible officer before making decisions that could affect their records.

What remains in effect after the September 2026 court ruling?

Because the federal court postponed the fixed admission period rule nationwide, the rule did not take effect on September 15, 2026. F, J, and I nonimmigrants remain under the existing admission framework for now. The postponed rule’s new extension requirement and shortened 30-day departure period are not currently in effect.

For F-1 students, the existing 60-day departure period following authorized completion generally remains available. Different rules may apply after an early withdrawal, termination, or other interruption. J-1 exchange visitors generally have a 30-day period following completion of the program, during which employment and exchange activities are not authorized. Individual records and circumstances should always be reviewed before relying on a departure period.

Why accurate records still matter

The court’s ruling preserved the current framework, but it did not relax the requirements for maintaining status. Students and exchange visitors should periodically review their I-94, passport, I-20 or DS-2019, and any employment authorization. Errors or outdated information are easier to address when identified early.

It is also important to avoid relying only on a visa stamp or a program end date. A lawful stay depends on continued compliance with the classification’s requirements, not on one document viewed in isolation.

The current framework may still change

The court postponed the rule while the case continues; it did not permanently withdraw or cancel it. The government may seek further review, and DHS may pursue additional rulemaking. International students and exchange visitors should therefore follow reliable updates while continuing to comply with the rules currently in effect.
